Applicatimi filed May 25, 1925, erlallbo, 32,7%, and in Sweden func i'he closing of bottles 4and the like .by means ol caps has'been made hitherto lessen- 'tiallyaiter two lines. Either the cap has been produced separatelyfin one or more ma i chines and it has been applied to the neck ot the bottle in a separate machine, or all operations have been executed in one and the same machine.. The method last mentioned hasailorded a considerable simplification ol l@ the worlz; with the advantages resulting theretrom," but in the form as used it is also iinn pairedby considerable4 inconveniences as s to be seenbelow. rlhe machines lor perform -ing the said method are adapted to bend the lil blanlr directly on the neclr of the bottle, that is to say, the neclr of the bottle serves as a mandrel in theY bending operation. The blank is stam L ed out over the mouth of the `bottle, genera ly from a strip, and then it is 2li immediately bent and tightened round the neel; ol the bottle.. However, this method has proved tobe anything but practical, especially because one is not able, on account olf the different width and shape of the necksl of the bottles, which are for the rest Aquite equal, to obtain the exactA accordance between the neck ol the bottle and the stamp which is necessary in corresponding members of bend ing tools ot the said type, if the plate is to be tree from folds and other unevennesses.n Consequently, .the caps are imperfectly bent and tightened round. the necks of the bottles and the bottles are badly closed.,

Another inconvenience of the method mentioned above lies in the fact that it does not admit any paching material in the shape ol' leaves, as 'lor instance'cork-leaves, to be in ser-ted inthe, capo The packing material is stamped out from a strip at thesame time as the cap blank and by the same toolsm For this reason it forms only a lining in the cap l andcannot do the same service as the leaves which act almost as packing material.

This invention has for its ob'ect to obviate le the said inconveniences by ena ling the ca s to be produced and 'applied to the neck of t ey bottle in one series and inone machine but' by using separate tools for the operation, so that the cap is produced by one tool, the paclring materlal, Where this is to be used, 1s inserted in the cap by another tool and the capping operation'is 'made by a third tool. By the op'erationsbe'ing distributed tri-separate tools possible to parlerai there with a :sie

precision quite inconceivable in the older machlnes and one will still reach, the same `speed ont the Work. The problem which this invention has for its object to solve does, however, not consist in the said tools being" collected in one and the same machine in lthe method and the means for transferring" the capsfrorn one tool to the other in order that the machine may worlr quite automatically. This problem has been very dicult to solve by reason of the fragility ol the capa and the difficulty ol the conveyer or conveyers grasping them steadily. By this invention this problem has, however, been solved in the simplest and most practical. manner, the cap engaging and carrying members or conveyers being adapted to displace pneu-u matically the caps finished or being made, for which purpose the conveyers communi-- cate by a piping with a suitable suction device, as for instance a blastn The manner in which this invention may be performed is to be seen from the following description and the accompanyingr drawing showing a cappingr machine which produces the cap and applies it to the neck of the bottle quite automatically?

The stamping and bending tool l ol the known construction, by means el which the blank is stamped out and bent is mounted in a slide-block 2 of the y:tranne il, 'the said l being moved upwards and downwards ual by a crank shalt t driven by an electr motor 50 or from another source el perlen On the table l5 located under the tool l the strip 6 is fed step by step by a suitable device to andunder the tool l from tbe'roll El grad@ ually as the blanks are being stamped out.

t block 2. The conveyer is mounted in the table lim v45 respectively the plate 20 is shape .for a reciprocating movement which is imparted to it by a pin fastened on the same and provided with av roll 14 engaging a curved groove of a suitable shape and provided in a disc 15 which is connected by gear to the motor and rotates always in one and the 'same direction during the running. The finished cap 56 is to be placed under the stamp 12 as shown in Fig. 6, thus in the position in which it leaves the stamping and bending tool 1 and is fastened on the neck of the bottle. Simultaneously, a cork leaf has been pushed under the cap. Then the stamp descends and places the cap just right above the packing leaf and a piston 16 acting from below and forcing the leaf into the cap which is thereby supported by the stamp 12. Motion is im;- parted to the piston 16 by a lever 17 located under the table 5 and actuated in its turn by a-cam 1,8 on the lower side of the disc 15.

After the packing leaf has been inserted in` the cap the same is moved into the capping tool. As usual the said tool comprises a clos- -ing mouth-piece 22 with an inner Ipiston 45 intended to press a ring of elastic material located in the mouth-piece round the neck of the bottle in order that the cap may be tightened round the same. The `bottle is placed on a supporting plate 2O movable in vertical direction so that it is able to push the neck of the bottle high enough into the mouth-piece 5 22. The supporting plate rests on an upright 21 located in the frame and movable in its longitudinal direction and connected with a two-armed lever 23 of the frame and actuated by 'an eccentric 24 driven by the motor by means of gear and a belt drive. The upright 21 is connected with the outer end of the lever 23 by links '7, one on each side of it. The inner end of the said lever is provided with a roll 25 which is pressed against the lower edge of the eccentric by the weight of the upright et cetera. Thus, the supporting plate is raised once for each revolution of the eccentric, the speed of whichis adjustedin such amanner that the said movement takes place each time a cap is inserted in the closing mouth-piece.

For adjusting the position of the raised bottle in relation to the elastic ring and the iston as a screw 26 which may be inserted for a greater or less distance into the upright 21. The bottles are moved successively to and from the supporting plate 20 as usual by means of a degice working automatically and notV shown ere. Y

The piston 45 is moved up' and down by an one-armed lever 27, a. lin -rod 28, a camdisc '23 and an eccentric 30. The lever 27 .ismounted in a member 31 screwed'on to the table 5. The cam-disc 29 and the eccentric 3Q are xed to the same shaft in the lower portion of the frame and they co-operate with the link-rod 28 in such a manner as to allow the cam-disc 29 to lower the same and the piston 45, and the eccentric 39 to raise both members.

As is to be seen from the aforesaid this invention refers especially to a device for transferring pneumatically the caps from one tool to the other by movable members which grasp the caps by suction in a quite reliable manner and hold them during the transfer. The manner in which the conveyers may preferably be executed according to this invention is dcscribed below.

The conveyers consist here of two tubes 32, 33 extending like the spokes of a wheel from a hollow head 34 located on the table 5 and movable round a vertical shaft 48, and by the said head they communicate with a suction pipe 36 leading to a blast 35. From the head 34 extends an arm 37 provided with a roll 38 adapted to co-operate with a cam-dise 39 mounted on the disc 15. By means of the said cam-disc and a spring 47-an ordinary shackle-spring may also be usedthe said tubes oscillate with equal intervals: the tube 32 between the stamps 1 and 12, the tube 33 between the stamp 12 and the mouth-piece 22 which is provided with an opening 40 (F ig. 5) for the insertion of the cap 56. The axes of the stamps 1 and 12 and ofthe mouth-piece are situated approximately at the same distance from the fulcrum of the conveyers 32, 33 and they have the same distance between them, the conveyers being so adjusted as to their length that when placed each in front of its tool they come very near to the cap located in or under the same. -lhen the cam-disc 39 does not actuate the arm 37, the spring 47 keeps the conveyers in their eXtreme position shown in Figure 3 where the mouth of the conveyer 32 is situated opposite the stamp 12 and the mouth of the conveyer 33 is located in the mouth-piece 22. The conveyers work in the following manner:

During the running of the machine the blast rotates with great speed whereby a compa-ratively strong suction is produced at the mouths of theconveyers which are adjusted by the cam-disc 39 each in front of its tool 1 and 12 respectively immediately before the caps are displaced. At the very instant when the stamp 1 releases the cap the same is car- Aried away by the air current and sticks at the -the packing leaf. The latter c ap provided with packing material 'is placed over the mouth of the bottle inthe mouth-piece and grasped by the bottle so that the nec-k of the latter during the upward movement of the bottle is put into the cap and then this cap is fastened to the neck of the bottle. Then the conveyers-a-re swung back by the camdisc as before and the course is repeated.

When producing and fastening-caps without packing leaves one conveyer only is used which is adapted to transfer the cap from the stamping tool directly. to the capping tool.

In order 'to prevent the cap from following the'conveyer 33 back to the stamp 12, in case the supply of bottles is interrupted,lthema chine may be provided with an obstacle to thercap which is arranged so as to allow the capto. be transferred from the stamp 12 but not backjto it. The saidobstacle may simply 'consist of 'a Arigid wire, metal strip 5l or the like tixedfto the arm 13. When the conveyer 33 is moved from the sta-mp l2 te the mouthpiece 22 the arm 13y occupies its upper position and holds the wire 5l out. of the path of the cap. When the conveyer is returned to -the stamp 12'the same is in its lower position and then holds the wire in the path of the cap. Caps caught by the said obstacle fall down under the table 5 through an opening 41 in the same According to the nature of the invention the same may be applied in different manners the means for-its performance maybe `varied. in several respectswithout the lidea underlying the same being given up.
